Flesh & Bone — Jonathan Maberry

Reeling from the devastation of Dust & Decay, Benny Imura and his friends plunge deep into the zombie-infested wastelands of the great Rot & Ruin. Benny, Nix, Lilah, and Chong journey through a fierce wilderness that was once America, searching for the jet they saw in the skies months ago. If that jet exists then humanity itself must have survived…somewhere. Finding it is their best hope for having a future and a life worth living.

But the Ruin is far more dangerous than any of them can imagine. Fierce animals hunt them. They come face to face with a death cult. And then there's the zombies -- swarms of them coming from the east, devouring everything in their paths. And these zoms are different. Faster, smarter, and infinitely more dangerous. Has the zombie plague mutated, or is there something far more sinister behind this new invasion of the living dead?

One thing Benny and his companions can't afford to forget: In the great Rot & Ruin, everything wants to kill you.
